This subject is well covered in theory by the late John Krause (SK es W8JK) in his famous book “Electromagnetics”. He is a late Professor of Electrical Engineering at the Ohio State University.
My father gave me a copy of this book when I was a student at Georgia Tech in the 1960’s. 73, John, W4NU Sent from my iPhone > On Nov 12, 2021, at 11:28 AM, Jose_Carlos <[email protected]> wrote: > > Ron > > The short answer is simple.
